METHOD OF ADJUSTING RADAR STATIONS OF AUTOMATIC CONTROL SYSTEM Russian patent published in 2014 - IPC G01S7/40 

FIELD: physics; control.

SUBSTANCE: invention can be used in automated air traffic control systems. The result is achieved due to that the disclosed method includes measuring coordinates of a reflecting object, followed by determining adjustment systematic errors; satellite navigators determining Cartesian coordinates of proper points of location of radar stations (X_n, Y_n); the radar station to be adjusted measuring Cartesian coordinates of an aerial object (X_On, Y_On); automatic control systems receiving, through an automatic dependent surveillance radio receiver, coordinates of the current location of the aerial object (X_AZNn, Y_AZNn); interpolating all received Cartesian coordinates to a single moment in time; mathematically averaging the obtained Cartesian coordinates of the aerial object interpolated to a single moment in time $$X_{mc}=\frac{X_{O1}+X_{O2}+\cdots +X_{ON}+X_{AZN}}{n+1};$$ $$Y_{mc}=\frac{Y_{O1}+Y_{O2}+\cdots +Y_{ON}+Y_{AZN}}{n+1}$$ calculating the adjustment for each of the radar stations to be adjusted $$\Delta {\beta }_n=arctg\left(\frac{Y_{on}-Y_n}{X_{on}-X_n}\right)-arctg\left(\frac{Y_{mc}-Y_n}{X_{mc}-X_n}\right)=arctg\left(\frac{\frac{Y_{on}-Y_n}{X_{on}-X_n}-\frac{Y_{mc}-Y_n}{X_{mc}-Y_n}}{1+\frac{Y_{on}-Y_n}{X_{on}-X_n}\cdot \frac{Y_{mc}-Y_n}{X_{mc}-X_n}}\right)$$ $$D_n=\sqrt{{\left(X_{mc}-X_n\right)}^2+{\left(Y_{mc}-Y_n\right)}^2}-\sqrt{{\left(X_{on}-X_n\right)}^2+{\left(Y_{on}-Y_n\right)}^2};$$ comparing the calculated adjustments Δβ_n, ΔD_n with the resolution of each of the radar stations to be adjusted and, if the adjustment is greater than the resolution of one of the radar stations to be adjusted, said radar station is re-tuned, and measurements and calculations are repeated until the adjustment value is less than the resolution of all radar stations to be adjusted.

EFFECT: high accuracy of adjustment.
